TL3116CPW

Comparators Overview

The TL3116CPW is an ultra-fast precision analog comparator manufactured by Texas Instruments, housed in an eight-pin Thin Shrink Small Outline (TSSOP) package. It operates from a single 5-V supply or dual ±5-V supplies with a typical positive supply current of 12.7 mA. The device features complementary push-pull outputs and input common-mode voltage that includes the negative rail for ground sensing applications. It offers low offset voltage and high gain, ensuring precise comparison capabilities while maintaining extremely fast propagation delays.

Comparators Feature Summary

• Ultra-fast operation achieving typical 10 ns propagation delay
• Low power consumption with only 12.7 mA typical supply current
• Complementary outputs capable of latching via the LATCH ENABLE terminal
• Input common-mode voltage extends to the negative rail

Comparators Applications

• Ground sensing circuits requiring negative rail input capability
• High-speed logic interfacing directly to TTL logic families
• Precision measurement systems utilizing tight offset voltage specifications
• Applications requiring output state retention through latch functionality

Comparators Procurement Notes

Verify component status as the TL3116CPW is listed as obsolete in official documentation. Confirm availability of active alternatives such as the TL3116IDR or TL3116IPWR which share similar electrical characteristics and packaging requirements for new designs.

Comparators Selection Notes

Select this comparator when high speed and low power are critical constraints. Ensure the design accommodates the TSSOP-8 package dimensions. Verify that the required operating temperature range aligns with the specific grade available, noting that the C-grade covers 0°C to 70°C while the I-grade supports -40°C to 85°C.

Comparators Part Context

This device belongs to the TL3116 series of ultra-fast comparators designed by Texas Instruments. It serves as a functional replacement for the LT1116, offering comparable high-speed performance with significantly reduced power consumption. The series is engineered for applications demanding rapid response times without excessive energy usage.

Comparators Replacement Considerations

The TL3116IDR and TL3116IPWR are confirmed functional replacements within the same family. These parts maintain identical pinouts and electrical specifications while offering extended industrial temperature ranges and active production status compared to the obsolete CPW variant.
